Advantages of electric control valve: In addition to the features of high reliability, full function and ultralight, electric control valve also has the following advantages:
⑴ The power supply is convenient and economical, which saves a series of costs for the establishment of the gas source station; ⑵ The complicated way of "pneumatic valve+electric valve positioner+air source" not only increases the cost, but also brings about a decline in reliability (the more links, the more factors of poor reliability); ⑶ From the economic point of view, in addition to the cost of the gas source station, it also saves the cost of the electric valve positioner: a good imported electric valve positioner is usually more than 5000~6000 yuan, preferably at the price of 8000~10000, which can basically buy back the above highly reliable electronic actuator; ⑷ The links are reduced, and the maintenance workload is correspondingly reduced.

Purchase of pneumatic butterfly valve requires a certain understanding of the price of the pneumatic butterfly valve, and then know how to do this part of work, know what kind of price of pneumatic ball valve is more reliable, what kind of pneumatic ball valve has guaranteed quality, and can ensure the results of work.
